As a maintenance technician at a hydraulic press manufacturer, the first step is to inspect the specific operating conditions of the hydraulic press's transmission system. Check if there are any issues with the working pressure, speed, hydraulic oil, leaks, and vibrations of the hydraulic press system software.

Listen to the hydraulic transmission system noise of the hydraulic press, such as: impact sounds; abnormal noise from the centrifugal pump of the hydraulic press; distinguish whether the hydraulic transmission system of the hydraulic press is operating normally.

By analyzing the heating, vibration, climbing, and connection tightness of the touch screen four-column hydraulic press, we can determine whether the operation of the fitness equipment components is running normally.

How to diagnose common faults on a four-column hydraulic press to avoid high oil temperature?

The four-column hydraulic press experiences significant load during forward feeding, but operates at a slower rate. During rapid advance and retreat, the load is lighter, but the operation speed is faster than during forward feeding. To enhance the working efficiency of the hydraulic press, oil can be chosen from secondary pumps or variable-frequency pumps. The hydraulic press is powered by variable plunger pump oil, taking a comprehensive consideration.

In addition, as the working pressure under standard load gradually increases during the operation of the hydraulic press, to ensure the safe operation of the hydraulic press under safety production standards, a variable plunger pump with a constant output power is selected for the speed control circuit. With the increase in working pressure, the pump's exhaust volume automatically decreases, maintaining the product of the working pressure and total flow rate as a constant, meaning the output power remains unchanged.

Therefore, when operating hydraulic presses, great attention should be paid to not overloading, which can prevent safety accidents caused by improper operation.
